I have 2 laying hens (ok, one is stubborn right now) and 22 9-week old laying chicks. I have been letting them all hang out together and they are getting along fine, although the chicks have a healthy respect for the big girls. My hens got into the medicated starter feed, and the babies got into the layer feed. Do I need to be concerned? I'm just coming off a withdrawal due to worming the adults, and don't want to go through more (but don't want to make my fam sick either). Advice?
